IMPROVEMENT IN CHAFE-IRONS FOR WHEELED VEHICLES.

Specification forming part of Letters Patent No. 127,645, dated June 4, 1872.

Specication describing certain Improvements in Ghafe-Irons for Wheeled Vehicles, invented by EDWARD P. ROCHE, of Bath, in the county of Sagadahoc and State of Maine.

This invention relates to that class of de` vices which are used as guards on wheeled vehicles to prevent the front wheels, in turning curves, from chang against the body thereof; and my improvement, having in view the greater perfection of that kind of these devices in which a roller serves as such a fender, consists, first, in the employment of .a luted roller, which possesses this important advantage over the smooth rollers now in use, that the receding portions-the principal ones-of its surface, when once galvanized or otherwise protected against corrosion, will remain thus coated, as the Wheels grind off only the coating of the projecting edges; secondly, in the combination, with the roller and its pintle, of

a horseshoe-spring, which, spanning one jaw of the supporting-frame, and carried by the pintle, presses with one of its legs, and with sufficient force, against one end of the roller to prevent the rattling of the latter against the frame by checking its endwise movements on the pintle; thirdly, in a projection formed on the outer jaw of the frame as an additional safeguard against chaflng of the wagon-body by the wheel should it from some cause turn past the end of the roller and jaw of the frame 5 and, lastly, in combining with the roller-pintle, which is, at its inner end, screwed into the frame, a spring with a V-notch in its end, t-

ting the corners of the head of the pintle, for

locking the latter when screwed home, which spring is pivoted to the frame, sotthat it may be swung out of the way of the head of the pintle; but, in being sprung over such head,

enters between projections on the frame, which prevent its turning.

Figure 1 is a plan view of a chafe-iron embodying my improvements. Fig. 2 is a vertical section on line a: of Fig. 1. Fig. 3 is a the axis of the wheels on the latter striking the surface of the rollers. The roller-frames, of which a right-handed one and a left-handed one are used on each vehicle, are composed of a plate, A, with a surface adapted to the form ofthe body of the particular style of wagon to which it is to be applied. From the rear end of this plate branches od' a curved arm or jaw, A1, which, being strengthened by the brace A2, serves as a support for the outer end of the roller-pintle C, the inner end of which is screwed 'into a screw-threaded eye in the lug A3 of the frame. The forward end lof the plate A is armed with apiece of steel, A4, to protect the softer metal of the plate against Wear by the wheel and guide the latter toward the roller B. The surface of this roller is fluted, and intended to be galvanized or painted to guard against its corrosion and its consequent mean appearance. WVere its surface made smooth this non-corrosive coat would soon be ground off by the wheel; Whereas in a iluted roller like mine, such coating will only be groundoff the projecting edges of the channels, and very little, comparatively, of the metal exposed to -corrosion. The metal of the roller is caseA hardened, and its eye is lined with a bush, B', of Babbitt or other noncorrosive and nonfrictional metal. Itis prevented from rattling against the frame by the spring D, which being of the curved form, best seen in Fig. 2, and held in place by the pintle C passing through perforations in its legs, straddles the jaw A1, and bears with one of its legs against the outer end of the roller with 4sufficient tension to prevent the endwise movements of the latter when left to itself. The pintle G, when screwed home, is locked by the spring E, which is pivoted to the jaw A1 at e, and constructed with a V-notch in its other end tting a corner of the head G of the pintle. This lockingspring is turned out of the Way while the pintle is being inserted, after which it is sprung over the head C', entering at the same time between the projections a a on the jaw A1, which prevent its turning of its own accord by the jarring of the vehicle. Another and longer projection, a', is formed on the jaw A1, which shall stop the wheel in case it turns toward thc carriagebody outside of the said jaw. l

E, in combination with cornered head of the piutle C and the projections a a on the jaw A1, substantiallyas and for the purpose specied.

In testimony whereof I have signed my name to this specification this 27th day of November, A. D. 1871, in the presence of two attesting witnesses.
